Edelbrock Marine 600 CFM Square-Bore Carburetor Performer 1409 — Air-Valve Secondary & Electric Choke

This Performer Series marine carburetor from Edelbrock combines a rugged all-aluminum square-bore body with an air-valve secondary and electric choke to deliver consistent fuel metering and quick transient response in marine environments. It features modified bowl venting, specially designed throttle shafts, and a tube-in-air-horn fuel-pump vent, all intended to resist corrosion and reduce typical marine installation headaches. The two-piece construction and ball-burnished finish make it lightweight and durable while eliminating fragile plastic components and power valves that can fail under demanding use.

How does this carburetor improve marine throttle response?

The 1409 Performer Series uses a revised secondary system and tuned accelerator pump components to sharpen mid-throttle and full-throttle transitions. The air-valve secondary design meters airflow smoothly, preventing bogging during sudden throttle openings, and the electric choke eases cold starts without manual enrichment.

• Revised secondary system for faster transient recovery
• Accelerator pump seal and calibrated metering rods pre-tuned for marine use
• Air-valve secondary for progressive airflow control
• Electric choke for consistent cold starting

What corrosion- and maintenance-friendly features are included?

Constructed entirely from aluminum with ball-burnished surfaces, this carburetor resists the corrosion common in marine atmospheres. It avoids vulnerable power valves and plastic parts, and its two-piece design reduces warping risk; metering rods are accessible without removing the carburetor, making routine tuning faster and cleaner.

• All-aluminum, ball-burnished construction minimizes corrosion
• No power valves or plastic components to fail
• Two-piece body reduces warping and simplifies service
• Metering rods changeable in seconds without removal

What installation and plumbing details should I expect?

The Performer 1409 is built with marine-specific fittings and venting: a 3/8-inch inverted flare fuel inlet and a tube-in-air-horn provision for a fuel pump vent. It also includes a 5-1/8-inch flame arrestor flange and a universal throttle lever to simplify hookup on most marine intake manifolds and control linkages.

• 3/8" inverted flare fuel inlet fitting for secure fuel connection
• Tube-in-air-horn for fuel pump venting to meet marine venting needs
• 5-1/8" flame arrestor flange for common marine filter mounting
• Universal throttle lever for flexible linkage installation

What performance limitations and warranty details apply?

Edelbrock designed this carburetor for gasoline-powered marine engines and tuned it accordingly; it does not include a broad power-valve system. The Performer line covers replacement and repair of the unit itself, while removal and installation costs are not covered. Edelbrock also backs the unit with a limited 90-day coverage for manufacturing-related issues.

• Calibrated for gasoline marine use only
• No replaceable power-valve system—simpler and more robust design
• Limited 90-day coverage for Edelbrock-supported defects
• Replacement/repair only; installation costs excluded

Who is this for: The Edelbrock 1409 Performer Series Marine carburetor is aimed at boat owners, marine engine builders, and performance technicians who want a straightforward, serviceable square-bore carburetor with strong transient response and fewer fragile components. It suits mid- to high-performance gasoline marine engines where reliable throttle response, corrosion resistance, and easy maintenance are priorities. If you need a lightweight, aluminum-carburetor replacement that’s easy to tune and built for marine-specific plumbing, this Performer 600 CFM unit is a practical choice.
